Business venture? Depends what you're doing. For charters, some people have shied away from the non-common rail Cummins due to noise. But, 1100 lbs of Cummins low and forward in the hull makes for a phenomenal riding hull in almost any conditions. My old Willard had a better hole shot than my friends H733 OTH with a stern mounted Yanmar 316 - even trimmed down, he went bow up when trying to accelerate quickly. Not so with the Willard. The con - the Willard topped out at 30 knots and he topped out at 42 knots.
Price? Expect to pay 4x for new over used for a Zodiac or Willard 7m. If you have time could you repower and old hull for cheaper? Of course.
